摘要:
The present invention is a method of and an apparatus for creating a pulsed stream of particles in a carrier means, such as air. A pre-metered stream of particles is accumulated in a pulsing chamber of a pulsing means by interrupting the stream of particles by a separator means, which interrupts the flow for a certain portion of the pulse period. The accumulated particles are then removed from the pulsing means by suction, such as by using an ejector. The invention is further directed to a kit or pack of individual absorbent articles which can be produced using the method and the apparatus.
摘要:
A method of producing absorbent articles, comprising: suspending particles in a gas carrier to form suspended particles; creating a series of pulses from the suspended particles, wherein each pulse in the series of pulses is created by: accumulating at least some of the suspended particles in a pulsing chamber to form accumulated particles on a rotary separator, and releasing at least some of the accumulated particles by rotating the rotary separator to create each pulse; and suctioning each pulse from the series of pulses onto a forming surface for the absorbent articles.
摘要:
A method of producing an absorbent article, including: metering particles at a predetermined flow rate to form a metered particle stream; carrying the metered particle stream in a carrier flow to form a carried particle stream; pulsing the carried particle stream to form a pulsed particle stream; and transferring a pulse from the pulsed particle stream onto a forming surface of the absorbent article.
摘要:
The present invention relates to absorbent articles, such as diapers and sanitary napkins, and topsheets useful for such articles. More specifically, the invention relates to an absorbent article (20) comprising: a liquid impervious backsheet (26); a liquid pervious topsheet (24) joined to said backsheet (26), said topsheet (24) having an inner surface oriented toward an interior of said article (20) and an outer surface oriented toward the skin of a wearer when said article is being worn, wherein at least a portion of said topsheet outer surface comprises a lotion an absorbent core (28) positioned between said topsheet (24) and said backsheet (26); wherein the lotion is applied to the liquid pervious topsheet (24) in the form of a pattern of a plurality of stripes (70), that are separated by a plurality of areas having no lotion; and the pattern of a plurality of stripes (70) is a discontinuous pattern.

The present invention relates to laminates and to absorbent articles, such as diapers and sanitary napkins, and production methods thereof. Specifically, the present invention is directed to an absorbent article (20) comprising an absorbent core (28) which is covered by a liquid pervious topsheet (24) on the wearer facing side of the core (28) and a liquid impervious backsheet (26) on the garment facing side of the core (28), the liquid impervious backsheet (26) having a longitudinal centerline and a transverse centerline, the transverse centerline defining a front half of the liquid impervious backsheet (26) and a rear half of the liquid impervious backsheet (26), the liquid impervious backsheet (26) also having a garment-facing side and a wearer-facing side, the liquid impervious backsheet (26) comprising at least three layers, a first layer (210) being comprised by the wearer facing side of the liquid impervious backsheet (26) and a second layer (220) being comprised by the garment facing side of the liquid impervious backsheet (26), the first layer (210) comprising a wearer-facing surface and a garment facing surface, the garment facing surface of the first layer (210) of the liquid impervious backsheet (26) comprises at least first indicia (250), said first indicia (250) being present in the front half of the liquid impervious backsheet (26) and said first indicia (250) not being present in the rear half of the liquid impervious backsheet (26), the second layer (220) of the liquid impervious backsheet (26) is provided from a woven or non-woven material, the liquid impervious backsheet (26) comprising a third layer (230) which is provided from a woven or non-woven material and the third layer (230) being comprised by the front half of the backsheet (26) thereby partially but not fully covering the garment facing surface of the second layer (220) of the liquid impervious backsheet (26) and the third layer (230) partially covering said first indicia (250), wherein the second and the third layer (230) in combination are translucent as to allow such that said first indicia (250) comprised by said first layer (210) are visible through said second and third layer (230) when looking at the absorbent article from the garment facing side of liquid impervious backsheet (26). The present invention is also directed to a laminate (200) and to a method of providing a laminate (200) useful as a liquid impermeable backsheet for an absorbent article.
